Groupizo is an online directory for discovering WhatsApp groups, bringing together listings from communities around the world. The site reports more than 1,738 groups spanning 52 countries, 49 cities and 29 categories, with listings searchable by topic, location or country. Categories cover a wide range of interests, including education, gaming, business, shopping, technology, entertainment, health, sports, friendship and community life.

The directory says each group link is checked before publication and monitored for invite status, with inactive links updated when identified. Visitors can browse listings without creating an account, and the service is free to use. Groupizo also invites users to submit groups for review and provides a way to report listings, helping keep its directory current. Additional features include country and city browsing, a blog, a visual gallery and community contributor rankings that recognize members whose submissions are approved. By organizing group invitations into searchable categories and locations, Groupizo aims to make it easier for people to find relevant WhatsApp communities and for group owners to share their invitations.
